Oversized and noisy
This fan blows a lot of air. Even with 90 percent of the suction pipe taped shut it overinflated my 27x95ft greenhouse with 44ft wide plastic on the top. The fan is very noisy and consumes a lot of power which might be suitable in a large greenhouse with different mounting hardware to dampen the vibrations and noise. We ended up making an adapter plate for a small computer cooling fan to run through this fan so we could use the hardware to get air between the plastic layers. We also ducted this through a plywood wall to the exterior and installed a vent cover on the hardware provided. Be sure to take off the metal burrs on the mounting hardware before putting it close to your plastic. We filed it smoother then covered the edges with duct tape.
